3.2 Area Measurement

1. Switch to Area Measurement mode. This is typically done by pressing the mode button until the area icon appears on the screen.
2. Measure the length of the first side (e.g., width) by pointing the laser and pressing the main button.
3. Measure the length of the second side (e.g., height) by pointing the laser and pressing the main button.
4. The device will automatically calculate and display the area.

3.3 Volume Measurement

1. Switch to Volume Measurement mode.
2. Measure the length, width, and height sequentially as prompted by the device's display.
3. The device will automatically calculate and display the volume.

3.4 Angle Measurement

1. Switch to Angle Measurement mode.
2. Follow the on-screen prompts to measure the necessary points to determine the angle.
3. The calculated angle will be displayed.

3.5 Pythagorean Measurement

The device supports various Pythagorean modes (e.g., single Pythagorean, double Pythagorean) to calculate indirect measurements. Refer to the on-screen icons for specific prompts for each Pythagorean function.

1. Select the desired Pythagorean mode.
2. Measure the required sides as indicated by the flashing segments on the display.
3. The device will calculate and display the unknown side.

4. Maintenance

4.1 Cleaning

• Wipe the device with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Ensure the laser lens and display are clean for optimal performance. Use a lens cleaning cloth if necessary.

4.2 Storage

• Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• The device features an aluminum-magnesium alloy casing for durability, but it should still be protected from drops and impacts.

4.3 Battery Care

• Charge the battery regularly, even if the device is not in frequent use, to maintain battery health.
• Avoid completely draining the battery before recharging.
• If storing for an extended period, charge the battery to approximately 50% before storage.

5. Troubleshooting

5.1 Device Not Powering On

• Ensure the battery is sufficiently charged. Connect the device to a USB charger and allow it to charge for at least 30 minutes before attempting to power on again.
• Press and hold the power button for several seconds to ensure proper power-on attempt.

5.2 Inaccurate Measurements or Laser Not Visible

• Ensure the laser lens is clean and free from dust or smudges.
• Measurements taken in bright sunlight or on highly reflective/absorbent surfaces may be less accurate or difficult to obtain. Try to measure in shaded areas or use a target plate if available.
• Verify that the measurement reference point (front or rear of the device) is correctly set for your application.

5.3 Short Battery Life

• Ensure the device is fully charged before use.
• Frequent use of the laser or backlight can consume battery faster.
• Battery performance can degrade over time. If battery life significantly shortens, consider contacting customer support.
